SAFETY-RAZOR.

Specification of Letters Patent.

Patented Sept. 21, 1920.

Application filed March 22, 1920. Serial No. 367,662.

To all whom it may concern:

Be it known that I, SETH G. MAPBY, a citizen of the United States,residing at Derby, county of New Haven, State of With the above andother objects in view,

the invention consists of the combination and arrangement of parts asnow tobe' fully described and hereinafter specifically claimed.

In the accompanying drawing forming a part of this specification,

Figure 1 is a side elevation of the improved safety razor, showing theblade resting on the blade support;

Fig. 2 a longitudinal section, showlng the blade adjustedto its farthestposition from the blade support;

Fig. 3 a perspective view, partly in section, of'the adjusting screw ofthe invention' Fig.4 a perspective view of the adjusting pin of theinvention; and

Fig. 5 is a perspective view of the set screw of the invention.

10 denotes. the shank or hollow handle, 11 the blade support and 12 theclampmg member of the safety razor of the invention. These parts are notnew, and, therefore, need but brief description to better explain thefeatures which I have invented. The blade support is" provided with athreaded opening 13 and the threaded outer end of the hollow handle isremovably connected therewith. The clamping member has a frictionalengaging portion 14: and an upright portion.l5, said upright portionbeing provided with an extension 16 hav1ng therein an'opening 17, largerthan the outer portion of the handle, through wh1ch sa d handle passes,as shown. ;Extens1on 16 is provided with a lug 26,wh1 ch bears againstan inwardly extending portion 27, shaped as shown, on the blade support.The blade support and clamping member have connection wlth each other asshown at 18 in Fig. 1, the connection preferably being by means ofbayonet slots inthe inner edge of the blade support and fingers on theclamping member. serted between the blade support and the frictionalengaging portion of the clamping member. To insert or remove the blade,the handle is grasped'and the upright portion of the clamping member ispressed toward said handle, the result being that the frictionalengaging portion is forced away from the blade support, as will bereadily understood. When'now the upright portion is released, the bladesupport and the frict1onal engaging portion of the clamping member arepressed toward each other, by reason of the bayonet interlocking meansbetween these parts, andthe bearing contact between lug 26 and inwardlyextending,

portion 27, to a suflicient extent to grip the blade and hold it, asdisclosed in Fig. 1.

20 denotes an adjusting pin having a head 21, 22 denotes an adjustlngscrew having a hollow head 23 to accommodate the head of the adjustingpin and a set screw 24, the adjusting screw being also provided with alongitudinal opening of smaller size, denoted by 25, through which theadjusting pin is adapted to loosely pass.

As will be apparent from Figs-1 and 2, the razor blade is adjustablefrom and toward the blade support by means of the adj usting screw. Itis essential that the maximum adjustment of the blade be fixed anddetermined, that is, the blade should not be capable of adjustment fromthe support a distance greaterthan a predetermined dis tance, thispredetermined distance being the maximum adjustment to whichthe razorshould be capable of being set for use. And further, when the blade isadjusted its farthest distance'from the blade support, the

head of the adjusting screw should rest 19 denotes a razor blade in-'NUFACTURIBNG COM- No. 1,288,045), h reinbefore referred to, and anadjusting pin which has a drive fit into an adjusting screw of thenature of the one disclosed in the present application, but theadjusting pins heretofore known have been; diflicult to manufacture,that is, in the manufacture of structure for adjusting the blades ofrazors of the present type-it has been necessary to maintain an almostimpossible. perfection in the manufacture of the parts, it havingheretofore been necessary to construct an adjusting pin of an exactandaccurate predetermined length to screwed into the hollow handle untilits head rests against the inner end of said handle, as it is shown inFig, 2, the ad usting, pin may then be inserted 1nto the ad justing'screw until its outer end. restsagainst the blade, oragainst thefrictional engaging portion ofthe clamping member, and its head lies inthe hollow head of the adjustingscrew but away from the lower wallthereof, and the Set screw may then be screwed into said' hollow headuntil the outer end of the adjusting pin has raised the blade apredetermined distance. from the blade support, or the adjusting pin maybe first inserted into the adjusting-screw, the setscrewthen loosely setin the hollow head, the adjustingscrew then screwed into the handleuntil its head rests against the inner end ofsaid handle, and thesetscrew may then be screwed into the hollow head to raise the blade asbefore. If desired, the set screw may be coated with shellac, or othersimilar substanee, before it is screwed into the hollow head, to makecertain that it will remain in the position to which it is inserted...It will benoted that the. set screw may be. inserted any desireddistance into the hollow head, but it may be added that the head of theadjusting pin shouldbe loosely arranged in the hollowhead so that whenthe adjusting screw is turned to adjust the blade, the adjusting pinwill have no turning movement. This is. an advantage notv found inadjusting meansof this character heretofore known, such previously'known adjusting means forcing the adjustingpinto turn to exert atwisting actioinon the blade, thereby forcing the blade f-roinitsproperposition between the blade support and the frictional engaging portionof the clamping member. The adjustin means hereinbefore fully describedforces the outer end of the adjusting pin against the under side of theblade without imparting thereto a rotary thrust.

it will be apparent that the present invention. affords a very simpleand accurate means for adjusting the blades of safety razors of thepresent or similar type.

What I claim is:

1; In a safety razor, a hollow handle, an adjusting screw disposedtherein and provided with'a hollow head, an adjusting pin carried bysaid adjusting screw and extending into said hollow handle and having ahead disposed in said hollow head, and a set screw disposed insaidhollow. head and adapted to bear against said head of said adjustingpin.
